Things you shouldn't do in Dubai
Be drunk in public. For Muslims, alcohol consumption is against the law but non-Muslims will be able to purchase alcoholic drinks in licensed bars, restaurants and hotels. However, just because you can drink doesn’t mean you should and certainly not to excess as public disorderliness is illegal for everyone regardless of faith.
Take photos of people without their explicit permission. It is considered rude to snap a photo of anyone without asking them first – this particularly applies to taking photos of local women.
Swear. Cussing and foul language are considered an offence and a number of foreigners have got themselves in trouble by making vulgar comments in the presence of an undercover police office. Keep it clean folks.
Insult Islam. This is probably the worst thing you can do in an Islamic country. Regardless of your personal opinion on Islam, do not say anything out loud that might be deemed as disrespectful. Blasphemy carries serious punishments so if you have any strong opinions on Islam, keep them to yourself.
Flaunt your homosexuality. Unfortunately, being gay in the UAE is still a crime and any public displays of affection can result in serious consequences. Cross-dressing is also illegal.
Use your left hand. This might seem like an odd rule but in Muslim culture the left hand is used for body hygiene and is therefore considered unclean. You should never shake hands or greet anyone with your left hand and you definitely shouldn’t be caught eating with it.
